Irish firm developing longer-lasting batteries

Longer-lasting phone and computer batteries could be on the way thanks to a €1.6m investment in a young Irish company.

The technology being developed by InfiniLED could also result in quicker diagnosis of health issues.

By discovering a way of generating more light using less energy in LEDs (light emitting diodes), which are about one-fifth the width of a strand of hair, the firm holds the key to reducing associated power usage.
